CORK-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No.`384,839, dated June 19,`1888.

Application tiled January 5, 1888. Serial No. 259,829. (No model.) n

l the following is a full, clear, and exact description, reference beinghad to the accom'- panying drawings, and to the letters of referencemarked thereon, which form part of this specification.

The purpose of the invention is to provide a cork-extractor simple inconstruction and con- Venient and effective in operation with which byone movement of an operating-lever the cork is extracted from thebottle, and by returning the lever to its normal position the .cork isremoved from the corkscrew without injury to the cork.

rIo these ends the invention consists in the matters hereinafterdescribed, and pointed out in the appended claims. l

In the drawings, Figure l represents in side elevation a corkextractorembodying the features of my invention. Fig. 2 is aview,mainly incentral vertical section, with certain of the operative parts removed,of the construction shown in said Fig. 1, said View being particularlyintended to illustrate the construction and operative arrangement of theinternal mechanism thereof. Fig. 3 is a view of the extractor, mainly invertical section, showing an alternative or slightly-modified form ofconstruction .and operative arrangement thereof, hereinafterparticularly referred to. Fig. 4 is a horizontal sectional detail of theextractor, taken on the line XX of said Figs. 2 and 3, showing theoperative arrangement within the cylinder of the screw which forms partof the corkscrew-shaft and the nut operating there-V with. Fig. 5 is aside elevation of the extractor, substantially illustrating the positionof the operating-lever and certain of the parts coacting therewith whenprimarily in the act of removing the cork from a bottle. Fig. 6 is anend elevation of the extractor when the operatinglever and the otherparts are in the position indicated in said Fig. 5. Fig. 7 is a top plandetail, in part in horizontal section, taken on the line X X of saidFig. 5. Fig. 8 is an elevation of the cap forming the upper terminationof the cylinder A, through which the stem of the corkscrew passes, andwhich forms a chamber for perpendicularly retain^ ing the pinion carriedby said stem in operative position with relation to the segmental rackwhich imparts motion thereto. v Referring by letter to the severalfigures of the drawings, in which like letters denote like parts, Aindicates a cylinder provided with a base portion, A', for attaching itto atable or other suitable support. The lower end of said cylinder isprovided integrally with a Haring portion, a, which forms a stop for theneck of the bottle from which a cork is to be extracted.

B represents an internallythreaded nut 1ocated within said cylinder andperpendieularly movable therein, desirably upon a guide lug l or key, b,formed integral with or fixed lto said cylinder, the said nut beingprovided with a corresponding keyway, t'.

C indicates an externallythreaded screw operatively set within said nutand provided,

.preferably integrally, with a corkscrew, C," at its lower end andanextension or stem, C,

at its other end, the said stem projecting from said cylinder throughsuitable openings formed in the capA2 thereof and. passing throughapinion, D, carried by said cap. The relative operative arrangement ofsaid pinion and stem 'is such that rotary motion is communicated to thestem through said pinion, and the stem is at the same time free to slidelongitudinally therethrough and independently of the rotary movementthereof. The preferred construc` tion of said parts, as shown inthedrawings, is as follows: The pinion D is held perpendicularly inposition within a horizontal recess, a2, formed within said cap A2. Thestem is provided with a longitudinal slot orkeyway, c', within whichworks a spline, d', carried by said pinion. A lever, E, pivotally heldby its lower portion to said cylinder A, carries a segmental rack, E,which meshes with said` pinion and obviously imparts rotary motionthereto. By preference a strap-piece, E2,

formed integrally with said rack, and likewise carried by said lever,works against the rear face of said cap A? and forms a desirable guidefor holding the rack in engagement with the pinion. A spiral spring, Es,fixed by one end to the outer end of the rack-piece E and by its otherend to the lower portion of the` cylinder A, is employed for holding thelever E in its normal position, as shown in Fig. 1, and for retractingor assisting in the retracting of the same from its downward position,as substantially shown in Fig. 5.

A lifting-arm, G, by preference in the shape of a yoke, as shown,pivotally held to an extension, e, of the lever E beyond the pivotalconnection ofsaid lever with the cylinder A, loosely embraces by itsupper portion, g, the stem C2, intermediate the cap A2 of the cylinderand the cap-nut c of said stem.

lVithin the cylinder A a coiled spring, H, is interposed betweenthe-*nut B and the cap A2, the olice of said spring being to exert aconstant downward tensional strain upon said nut. The keyway in the nutterminating near the upper end thereof, a shoulder is thereby formed,which engages with the guide lug or key b when the nut reaches the limitof its downward motion, and thus prevents the nut from being driven outof the cylinder by the spring.

In operation a bottle is placed in position with its neck Y inserted inthe flaring portion a of the cylinder. The lever E being carrieddownwardly, the rack E rotates the pinion D, which in turn impartsthrough the stem C2 rotary motion to the corkscrew C. The nut B beingcapable only of longitudinal movement and being held to the lowest limitof its downward movement by the spring H, the screw C,workingtherein,carries the corkscrew downwardly toward and intothe cork in theneck of the bottle until the lever has described approximately abouttwo-thirdsof its downward travel, at which time the arm G and thedownwardly-moving cap-nut @come in contact. Further downward movement ofthe lever causes the arm G to move upwardly, and to therefore move thecorkscrew in the same direction, a twisting and pulling motion beingsimultaneously given thereto by means of the concurrent operation of thepinion and the arm, and the cork being readily drawn from the bottle. Areverse movement of the lever E carries the arm G downwardly. The pinionD, being driven in a reverse direction by the rack, causes the corkscrewto be withdrawn from t-he cork, the nutB, which was carried upwardlywith the screw C as the action of the arm moved the same upwardly, beingreturned to its normal position by the tension of the spring H.

In Fig. 2 the nut B is shown to be provided with a counterbored lowerextension, which terminates when in normal position at or about thelower end ofthe corkscrew C' and the upper termination of the flaringportion a of the cylinder, occupying such position with relation to thecylinder through the downward and forward rotary movement ofthecorkscrew and materially assisting in the removal of the cork from thescrew when the rotary motion thereof is reversed. In Fig. 3 the said nutis shown as not being provided with such extension, and as thereforebeing operative t0 simply guide the corkscrew by means ofthe screw Cthrough its several described movements, the cork ony being drawn fromVthe bottle iinpinging against the annular shoulder n, formed at theupper termination of a counterbored chamber formed in the lower endofthe cylinder contiguous to the flaring portion c as the rotarymovement of the corkscrew is reversed.
